Your menu stays

Your menu lives in your store’s Shopify Navigation. Menus Uncomplicated renders and enriches that menu - it never moves your menu into our system. When you uninstall the app, your navigation is exactly as it was before you installed it: the same menus, the same items, in the same order.

What about the decorations you added?

The decorations you added - images, badges and featured collections - are stored as metafields on your shop, not on our servers. Because they belong to your shop, they persist after you uninstall.

These stored metafields are completely inert - once the app is removed they have no effect on your store or storefront in any way, and there is nothing you need to do. They’re ready to be picked up again if you ever reinstall. If you really want them cleared, just contact our support team and we will remove them for you.
